Why giraffes will become short again?

More about the book

The evolution of mammals is traced from their origins as small bulk animals to their adaptation against increasing gravity. With the development of 4-chambered hearts and robust circulatory systems, mammals initially grew larger. However, as gravity intensified, they faced challenges that led to a gradual reduction in size, a trend that is expected to continue. This exploration delves into the biological and environmental factors influencing the ongoing process of body size minimization in mammals.
